Subwoofer Placement; Connecting The Subwoofer - JBL SP-150 Manuel D'instruction

• We recommend that the subwoofer be unplugged from the wall during lightning storms, and when not used
for an extended period of time.
• Do not use wherever there is a risk that the subwoofer may come into contact with water or excessive \
moisture such as near pools, bathtubs and wet basements.
• In the event of a malfunction, do not attempt to service the product yourself. Please contact your JBL dealer.
Before making connections to your receiver/processor, please make sure the subwoofer is unplugged from
the wall and that your audio/video receiver or surround processor is in the "Off" position.

SUBWOOFER PLACEMENT

Low frequency sound is generally non-directional. This allows for
great flexibility in the placing of a subwoofer, as it is difficult for the
human ear to discern where the low frequency sound originates.
Ideally, however, the subwoofer will be placed on the same plane
as the main left/right speakers. (Figure 1.)
Placement Tip:
Bass output varies with position. For more bass output, place the sub-
woofer near a wall boundary. Placing the subwoofer closer to a corner
of the room will increase the bass output considerably.

CONNECTING THE SUBWOOFER

A) LINE LEVEL CONNECTION - (ALSO KNOWS AS "LOW-LEVEL").
Connect the audio/video receiver or processor's subwoofer output, to the JBL Subwoofer's line level input.
(Optionally, you may connect your Left/Right speakers as shown below.)
B) SPEAKER LEVEL CONNECTION - (ALSO KNOWS AS "LOW-LEVEL").
Connect the audio/video receiver's Left/Right main channel outputs to the JBL L/R Speaker Level Inputs. Make sure
to connect "+" (Red) to "+" (Red), and "-" ( Black) to "-" (Black). (Optionally, you may connect your Left/Right speakers
as shown below.)
High-Level connection Tip:
When using small satellite speakers, connecting the JBL subwoofer with the Speaker Level inputs and then
connecting L/R satellites to the "Speaker out" will automatically limit the low frequency sent to the small speakers
with the high-pass filter built into the JBL subwoofer. This is helpful to small speakers, in that they will then not be required
to reproduce frequencies that may be beyond their operating range. You may now plug your subwoofer's power cord to the
A/C wall outlet.
Figure 1. Do not block the tuned port: Allow a
few inches of space behind the subwoofer.
